' RAILWAY-BAIL.

I, WILLIAM W. HECK, a at Steel-ton, in the county of Dauphin and tate ofPennsylvania, have invented 'certain new and useful Improvements' inRailway-Rails, of which the following is a specification, refhad thereinto the accompany- Be it known that in 'drawing y his invention relatesbroadly to railway rails and more specifically to rails of the sectionaltype in which a tread-component is removably 'supported in' a base-cornponent.

The primaryiobject of the invention isto provide arailwa'y rail in whicha treadcomponent is supported in a base-component in such manner thatlow pints are practically precliided whereby an absolutelylwithoutfdisturbng the baseicomponents 1n which nit is' y supported.

points of reatest strain.

A still rther object of the invention is to provide a sectional railwayrail, includn base and tread-components aggronp relatively as t0 causethe 'base-component, to support the tread-com onent atthree points at`least andv independent of the i securing bolts, whereby shearing ofthelatter is prevented.

The invention seeks in general to provide.

a rail-'structure which is particularly?adaptv ed for use onvrailwayswhere thev traiiic is heavylor the speed of the trains is high, andwhich structure, from0 an operative stand# point, will in practical usepossess a hi -h degree 'oeiliciencyg ri ``dity, and dura and which,.structura ly consideredywill be of reat simplicity. i y ther objectsand advantages are also present iny the. invention and these will bemore or less obvious from the annexed draw.` ings and the followingdescri tion.

' he invention resides broad yin the fea tures of constructioln'and inthe aggroup- 'ment of the components thereof, all as will ility, i.

be exemplified in .the construction lherein- Y after set forth, and thescope of application of which 4will be indicated inthe c aimhereto-appended. A That the invention may be clearly com prehended,drawings yillustratin some :of the possible embodiments anduti lzatio'nsof the same are heretoappended as a -pa-rt l01E this disclosure; and invwhich drawings- Figure 1 is a view in perspective, partly in section,of a` railway-rail constructed 1n s accordance with my invention;

Referring to these drawings, the referencen vertical transverse@ acc ytion 'ofthe structure; and y fi" ect of the invention is to w theruil-somnoaearin' numeral 1 desi nates, generally, a base-portion which,in t is instance, is provided with an elongated groove '2, the walls 3of which converge downwardly to present a substantially flat bottom 4,vThe walls 3 terminate in outspreading flanges 5, a substantial ortionof the upper surface of each of w ich is curved, as at 6. These curvedsurfaces, as best seen in Figui, form arcuate continuations orextensions of the diver ing walls and extend to the tips or outer e gesof the flanges into approximate alinement with the sides of ahead-,portion on a com' onent about to be described. It is to be 'unerstood that a, series'of these base-portions 1 are tobe arranged in analined and abutting relation so that the grooves 2 of each twocomponents also aline and are practically continuous.

The reference-character 7 designates, generally, the-.tread-componentwhich, in this instance, is shown as including a head-portion 8 havinits under-surfaces 9 rolled to conform to t e contour of theuppersurface ofthe flanges 5 of the base-component. The head-'portionincludes a tread-.surface and lsides 9 spaced apart in approximateparallelism. The under surfaces of the tread- `A each having :a bearin-component are curved, as at 10, and lthese curved surfaces extend inarcuate arrangement from the `sides of lthe head-portion to a point, 11,where they terminate in diverging sides of a substantially V-shapedtongue 12 formedonthe tread-component. The curved portions andVwedge-portion of each component are arranged to it snugly together, in acorrespondingly shaped portion of t e other. The lower edge 13 of thetongue is substantially square and adapted to rest on the bottom 4 ofthe groovefin"thebase-component. s

, Each base-component is, preferably and as shown, provided with eightspaced-apart boltehole's14,`which,.as shown in Figs. 3 and .componentlis 5, are preferably elongated, while each treadrovided with an equalnumber of bolt-holes 15. The number ofholes may, ofcourse, -b'e varied.Bolts 16 are disposed in these bolt-holes 14 and 15 and have their nuts17, orasubstantial portion thereof, rojecting beyond theplane of theside- '4 sur ace of the tread-com onent, whereby such nuts mayybetighteneonvenientl Itis to be understood that the two a utting ends ofeachtread-componentare to occupy aposition intermediate of the` ends ofthe basecomponent which supports them; from-.which it follows that theabutting ends of the base-componentbreak joints with thetreadcomponents.

The elongated'formofythe holes 14 in -the "base-'component permitscontraction and ex- '.pansion of the-ralls.

In Fig.' 5, I have disclosed the manner of connecting my improved railto a frog or slight bending of the metal at t add to fthe resiliency. ofthe flanges. These grooves, in conjunctlon with the curved bearingsurfaces of the components, ermit a lrfat point and this allows forexpansion and contraction of the parts without binding between the headand base flanges.

By reason of the aggroupment of the components 'and the manner ofclamping them together by the bolts, as already described, theobjectlonable feature of low joints is prevented, and this is animportant consideration in railroad construction. Moreover, by reason ofthe feature of removability of the tread-components from theirsupporting base-components, these tread-components are replaceable, orinterchangeable.- Infact, they may be turned end for end, if desired.

It is also to be understood that it is a feature of my invention-notv toundercut or otherwise form any portion ofthe` components in such manneras to weaken them at any point. A l' It is also a' feature of `myinvention to mount the tread-component in the basecomponent in such`manner that the former will be supported b the latter at three pointsat least, name y, bythe flanges engaging the under surfaces 9 of theheadportion and by the lower edge 13 of the tongue seating onv thebottom 4 of the groove in the-base-component.-

B -reason of the :fact that the walls 3 of the ase-component are notarranged in parallelism, it is' not so essential that the tongue ponent.Moreover, -this arrangement avoids any tendenc of the bolts 16 to ca`any of this we ig t or strain.; hence the.u
